Where can I get the photo of “Introduction to automata theory, languages and computation” by Hopcroft and Ullman '79 (first edition) cover in order to be able to read all the phrases placed on the cover? Obviously the ones that gave me Google.Images (from Wikipedia, Amazon and others) do not allow this.

    $\begingroup$ It is as offtopic as any basic question, Suresh. $\endgroup$

    $\begingroup$ I think such a question would be allowed on MathOverflow, and hence I am in favour of allowing it here. $\endgroup$ Oct 28, 2010 at 17:18

    $\begingroup$ In general I think we should not encourage questions of the form "can anyone send me a scan/photocopy/photo of this-and-that article/book". Such questions are of little general interest, and there are also legal/copyright issues. This particular question is a borderline case, but let's not push it too far. $\endgroup$ Oct 28, 2010 at 17:39

1 Answer 1


Update: High resolution cover can be found here. (via Artem)


A: Pushdown Automata
B: Regular Expressions
C: Context Free Languages
D: Finite Automata
E: Mathematical Truth
F: NP-Complete Problems
G: Turing Machines
H: Time/Space Complexity
  • $\begingroup$ My main objective is to get such a photo, that I could read all the phrases placed on the front cover. As of the Wikipedia's version — I can only see «NP-complete problems», so it's not admissible. $\endgroup$ Oct 28, 2010 at 17:36

    $\begingroup$ @Michael to demonstrate to the students attending “automata and languages” classes (I'm acting as a TA on it). The cover is a bit a piece of CS history (Cinderella book standing near the Dragon book, Camel book and so on...) $\endgroup$ Oct 28, 2010 at 18:25

    $\begingroup$ @Artem, Nobody in your department has a copy of the book you can scan? For shame! (You can contact me offline if nobody else has already sent you what you need.) $\endgroup$

    $\begingroup$ @Artem Rube Goldberg machines have everything to do with CS! Think about the process that brings these words from my fingers to your eyeballs. The ENTIRE process. Throw in a little TCP/IP by carrier pigeon, and you've got the Platonic Ideal Rube Goldberg Machine. $\endgroup$

    $\begingroup$ The systematic examination of themes by means of a diagram is highly information-dense; I approve. All we need now is a discussion of the social prophecy and aspects of moral philosophy embodied by the illustration, and we are on the way to becoming a Theory site! (See meta.cstheory.stackexchange.com/questions/1/… for the reference.) $\endgroup$ Oct 29, 2010 at 9:45
